BACKGROUND OF THE INVENTION

As a user accumulates various instruments under the same underlying, it can get difficult to understand the aggregate position because of the complex interrelationships of stock and various option contracts. Also, given this state of complexity, it can be difficult to formulate trades—for example, if the user wanted to trade multiple legs at a time the user would have to figure out standard combinations of those legs by hand. In addition, as the user makes trades the ability to formulate and track spread holdings can be difficult because the make-up of the possible component strategies can change.

Unless stated otherwise, a component such as a processor or a memory described as being configured to perform a task may be implemented as a general component that is temporarily configured to perform the task at a given time or a specific component that is manufactured to perform the task. As used herein, the term ‘processor’ refers to one or more devices, circuits, and/or processing cores configured to process data, such as computer program instructions.

A detailed description of one or more embodiments of the invention is provided below along with accompanying figures that illustrate the principles of the invention. The invention is described in connection with such embodiments, but the invention is not limited to any embodiment. The scope of the invention is limited only by the claims and the invention encompasses numerous alternatives, modifications and equivalents. Numerous specific details are set forth in the following description in order to provide a thorough understanding of the invention. These details are provided for the purpose of example and the invention may be practiced according to the claims without some or all of these specific details. For the purpose of clarity, technical material that is known in the technical fields related to the invention has not been described in detail so that the invention is not unnecessarily obscured.

A system for automatic strategy grouping for a trading system is disclosed. An indication is received to automatically group a set of investment instruments. A set of possible strategies is determined from the set of investment instruments. A set of groupings of strategies is determined from the set of possible strategies. One or more selected groupings is determined from the set of groupings of strategies based at least in part on a selection criteria.

In some embodiments, a trading system automatically assigns a grouping of standard strategies to a set of individual instruments related to the same underlying instrument held by a user. In various embodiments, the investment instrument comprises one or more of the following: an option, contract on an underlying investment instrument, a stock, a mutual fund, an exchange traded fund, an index, a currency, an asset, or any other appropriate investment instrument. In some embodiments, a standard strategy comprises a position in a spread or an individual instrument. In some embodiments, a standard strategy comprises a combination of being long or short with one or more of the following: a call, a put and/or the underlying instrument (e.g., a stock, index or fund on which the call or put option is associated with).

As the option industry has evolved over the last several decades, some strategies have become so popular they are “standard” to the industry in terms of component instruments that make up the strategy. In various embodiments, an automated strategy grouping system triggers whenever the trading system recognizes that an order has filled in the market. Upon triggering, an algorithm and a defined (but updateable) set of standard strategies is used to find the range of possible strategy groupings (e.g., a set of possible strategies) that can be created by grouping into standard strategies the held instruments related to the same underlying (e.g., investment instrument) as the filled order. From the range of possible strategy groupings, an automated strategy grouping system selects the grouping the user is most likely to want, using a tie-breaker system if necessary. Automated Strategy Grouping then updates a user interface automatically so that the user may monitor and trade the strategies in the grouping as if they were single instruments. In some embodiments, the automated strategy grouping system is invoked interactively by a user who can request at any time to see the range of possible groupings for the positions held for any underlying and choose from the range a grouping to apply to the held positions.

In some embodiments, an automated grouping system offers several major advantages to a user of a trading system. For example, an automated grouping system saves the user time that would be spent accessing, monitoring and operating on instruments individually which can be better managed as groups of strategies. With automated grouping of strategies, operations can easily be performed directly on the strategies where the operations can comprise one or more of the following: receiving or requesting a quote on a selected strategy in the grouping, trading a selected strategy in the grouping, viewing the risk metrics on a selected strategy in the grouping. Another advantage of the automated grouping system is that it helps the user manage larger and more complex portfolios since the possible permutations of strategies that can be created from held positions can be large and unintuitive when a human eye (e.g., the user) examines a list of holdings.

In some embodiments, automatic strategy grouping can be executed from an Action Menu by clicking Grouping. The Alternative Grouping dialog will then pop up. In this dialog, the user may generate and select an alternate grouping of strategies. In some embodiments, automatic strategy grouping is also called without user intervention to return the strategy grouping the user is most likely to want automatically.

FIG. 1 is a flow diagram illustrating an embodiment of the process of forming a strategy from individual instruments. In the example shown, position 101 comprises an instrument, where the instrument is Google stock (symbol GOOG) and where position 101 is long 100 shares of Google stock. Position 102 comprises a long 1 September, 2009 put option with a strike price of 510. Process 103 forms a single strategy from held position 101 (the long stock position) and position 102 (the long put option position). Strategy 104 indicates the result of forming a strategy, in this case the strategy formed includes leg 105 associated with position 101 and leg 106 associated with position 102 and comprises a long “protective put” position with an expiration of September 2009 and a strike price of 510.

FIG. 2 is a diagram illustrating an embodiment of an Action Menu. In some embodiments, the action menu is invoked from display indicating a strategy to provide actions for operating on the strategy. In the example shown, strategy 201 indicates a strategy in a line of a table that when clicked on, invokes Action Menu 202. Icon 203 comprises an icon indicative of a risk profile and a profit and loss indicator for strategy 201.

FIG. 10 is a flow diagram illustrating an embodiment of a process for automated strategy grouping. In the example shown, in 1001 a user places an order. In 1002, the order is vetted. For example, vetting the order comprises checking that the order is a valid order and that the order is acceptable within a user's account constraints and available funds for the user. In 1003, in the event that the order is OK, store the order to a database and provide the order to the market. In some embodiments, the order is stored to a storage system that is not a database. In 1004, the order is accepted, and the order waits for a fill. In 1005, the order is filled. In 1006, an indication of fill is received, and the fill is accepted. For example, acceptance of the fill includes storing the fill in the database or storage system. In 1007, an account associated with the fill is determined. In 1008, provide all positions in the account associated with the underlying investment instrument of filled order to automated strategy grouping system. For example, the existing positions the user is holding are gathered from the database or storage system for the underlying and provided to the grouping algorithm of an automated strategy grouping system. In 1009, the grouping algorithm generates the possible strategy groupings. In 1010, the grouping algorithm selects grouping based on rule(s). In 1011, selected grouping is applied to positions in account related to the underlying. In some embodiments, the positions in account are stored in the back end system. In 1012, it is indicated that updated positions are available. In some embodiments, the front end is provided an indication that updated positions are available so that the front end can initiate an update process for its position display. In 1013, front end makes a call to update positions (no user intervention in this process). In some embodiments, the front end updates its display of positions and/or groupings automatically after receiving an indication that update positions/groupings are available. In 1014, updated positions are provided. In some embodiments, the updated positions and/or groupings are sent from the back end to the front end. In 1015, the system updates the user interface with a display of the grouped positions.

FIG. 11 is a flow diagram illustrating an embodiment of the process for automatically finding groups of strategies and selecting a desired strategy. In the example shown, in 1101 the range of strategies that are possible are determined given the held instruments for the underlying. In some embodiments, a set of possible strategies are determined based, at least in part, on a set of investment instruments that are held within an account or associated with a user. In 1102, the set of groupings is determined for the underlying. In some embodiments, a set of groupings of strategies is determined from the set of possible strategies. In some embodiments, the set of grouping of strategies comprises all possible combination of groupings. In 1103, the set of groupings is arranged in order of desirability and a most desired grouping or the ordered list of groupings is returned. In some embodiments, one or more selected groupings from the set of groupings of strategies is determined based at least in part on a selection criteria. In some embodiments, based at least in part on a rule (e.g., a strategy grouping with the fewest possible members, a strategy grouping with members that have strategies of only certain predetermined types, etc.), a strategy grouping is selected.

FIG. 12 is a flow diagram illustrating an embodiment of a process for determining possible strategies from a set of instruments for an underlying. In some embodiments, the process of FIG. 12 is used to implement 1101 of FIG. 11. In the example shown, in 1201 all the instruments held for an underlying are retrieved. In some embodiments, positions and/or groupings of instruments associated with an underlying investment and associated with an account or user are retrieved from the database storage system (e.g., a storage system associated with the back end system). In 1202, a code is created for each instrument based on attributes that characterize the instrument. In some embodiments, the attributes that characterize each instrument are encoded using a representation that enables a unique representation for an instrument. In 1203, instruments are combined using the coded attributes, and all the combinations that are standard strategies are listed. For example, standard strategies include but are not limited to call options, put options, underlying instruments such as stock or an exchange traded fund (ETF), covered calls, protective puts, verticals, straddles, strangles, calendars, diagonals, butterflies, condors, iron condors, iron butterflies, backspreads, combinations, synthetic stock, collars and vertical spread spreads.

FIG. 13 is a flow diagram illustrating an embodiment of a process for determining the set of possible groupings from a set of possible strategies for an underlying. In some embodiments, the process of FIG. 13 is used to implement 1102 of FIG. 11. In the example shown, in 1301 groups starting with the strategy with the most legs are formed. In 1302, successive strategies are chosen by attempting to form strategies with the remaining positions. In 1303, iterate until the one-legged strategies are exhausted.

FIG. 14 is a flow diagram illustrating an embodiment of a process for arranging the set of possible groupings for an underlying in an order of desirability according to a criterion. In some embodiments, the process of FIG. 14 is used to implement 1103 of FIG. 11. In the example shown, in 1401 a criterion of desirability is selected. In some embodiments, the criterion of desirability comprises a default criterion (e.g., a strategy group with the least number of elements in the group). In various embodiments, criteria of desirability comprise, but are not limited to, finding the grouping with the least number of strategies, finding groupings that limit the number of instruments that are in any of the strategies in the group and finding groupings that only allow one specific multi-instrument strategy plus the one-instrument strategies, or any other appropriate criteria. In 1402, the set of groupings is arranged in order according to the desirability criterion from most desirable to least desirable. In 1403, the most desirable grouping or the ordered list of groupings is returned depending on the calling function's request.

In various embodiments, the desirability criteria or prioritization or ranking of the criteria is selected by a user. For example, a user provides an ordered ranking or prioritized rule(s) indicating the desirability of strategies.

In some embodiments, the automatic strategy grouping algorithm comprises the algorithm described below. In some embodiments, the portfolio is arranged by underlying security and the holdings related to one underlying are organized at a time.

Start of Automatic Strategy Grouping Algorithm:

The system specifies via a call to the algorithm whether the algorithm should return one preferred grouping of strategies or a list of the most preferred groupings. A list of the most preferred groupings is used in some embodiments for enabling a user to select a user preferred grouping. If a list is requested, one member of the list will always be the grouping that is comprised of each individual instrument as a member of the group.

1) Determine the Range of Possible Strategies for the Underlying

For the selected underlying, determine the possible standard strategies that can be made from the individual instruments (legs) held for this underlying. Individual instruments include, but are not limited to, any of the following six items:

-   -   1. Long underlying     -   2. Long call     -   3. Long put     -   4. Short underlying     -   5. Short call     -   6. Short put

Let the set of all possible standard strategies that can be made be called the Range of Possible Strategies. The Range of Possible Strategies is a subset of the working set of standard strategies. The working set of strategies includes individual leg strategies, such as a long call, and multi-leg strategies such as a vertical strategy which contains both a long and a short call. The working set of strategies is variable, but generally conforms to strategies that are currently popular. Examples from the set of strategies include vertical strategies, diagonal strategies, butterflies, condors, straddles, strangles, iron condors, collars, buy-writes, etc.

The Range of Possible Strategies are determined based on a set of standard strategies using the following technique:

-   -   A. A strategy has four attributes which will uniquely define a         standard strategy within a defined set of working standard         strategies. By identifying four attributes for the strategy a         unique representation is generated and expressed in the form of         a Code. The four attributes are:         -   a. The number of positions in the strategy (number of legs).             For example, for a long vertical call strategy the number of             legs is 2.         -   b. The type and side of each position in the strategy.             Possible types would include, but not be limited to, calls,             puts, stock and exchange traded funds (ETF's). Possible             sides would include being Long or being Short. Thus, a long             vertical call strategy would have a type/side attribute that             can be expressed as LCSC, or Long Call Short Call.         -   c. The relationship of the strike prices in the positions.             For a long vertical call strategy, the strike of the long             call is less than the strike of the short call, or             LC(strike)<SC(strike)         -   d. The relationship of the expiration dates in the             positions. For a long vertical call strategy the expirations             are the same, or LC(expiry)=SC(expiry)     -   B. This Code is unique for all the standard strategies and is         used as an identifier for the standard strategy. For example,         for a long vertical call strategy the code comprises 2LCSC         , to mean a 2 legged strategy comprising a long call and a short         call where the strike of the long call is less than the strike         of the short call and the expiration dates are the same.     -   C. The basic steps in identifying the attributes comprises:         -   a. Identify the number of positions involved in the             strategy.         -   b. Take positions one by one and identify the attributes of             type and side         -   c. Based on number of components/positions, comparison on             strike price and expiration needs to be performed.         -   d. Find the relationship between the strikes         -   e. Find the relationship between the expirations     -   D. To determine the Range of Possible Strategies, iterate         through the set of instruments held for the underlying by         combining the instruments into possible strategies and testing         to see if they are standard strategies. Any 1 instrument taken         by itself is always a standard strategy and a member of the         Range of Possible Strategies.         2) Determine the Set of Groupings for the Underlying

For the Range of Possible Strategies, determine all possible groupings of strategies that are combined to exactly make up the holdings for the underlying. Call this set of groupings the Set of Groupings.

The Set of Groupings is determined as follows:

-   -   A. Start with the standard strategy in the Range of Possible         Strategies that has the most legs. Form groups such that group         members are standard strategies. Successive strategies for the         group are chosen by attempting to form strategies with the         remaining positions that are members of the Range of Possible         Strategies that have the most legs. As the greater number of leg         possibilities are eliminated, the lesser number of leg         strategies are used down to the one-legged choices. Iterate the         process by starting with the next-most complex strategy in the         Range of Possible Strategies.     -   B. For making strategies, it's required that every held position         be a member of a strategy. There are no left over positions of a         held instrument (e.g., no positions that are not represented in         a grouping).         3) Arrange the Set of Groupings in Order of Preference

Select a criterion of desirability of a grouping and arrange the Set of Groupings into priority order from most desirable to least desirable. Then, return either the most desirable grouping (for automated grouping functions) or the list of the top groupings in priority order for functions where the user can pick the desired group. Do this as follows:

-   -   A. Choose a criterion for what makes the most desirable set of         groupings. Various criteria include, but are not limited to,         finding the grouping with the least number of strategies,         finding groupings that limit the number of instruments that can         be in any of the strategies in the group and finding groupings         that only allow one specific multi-instrument strategy plus the         one-instrument strategies.     -   B. Arrange the groupings in the Set of Groupings in order from         the most desirable groupings to the least desirable groupings.     -   C. Depending on the calling function, return the most desirable         grouping or a list of most desirable groupings (a list would be         returned, for example, for scenarios when the user is hand pick         a grouping). If a list is requested, the list always includes         the grouping that is comprised of each individual instrument as         a member of the group.         End:
